Grades

KC643M

Coated fine-grain grade with PVD multilayer (AlTiN). KC643M™ is a very thin and hard PVD coating particularly suited for cutting steel, cast iron, stainless steel (wet), and titanium (wet). This grade can be used for materials with hardness up to 52 HRC.

Features and benefits

Keyway cutter for slot machining of shaft to hub connections.
For production of key slots according to ISO standards.
Roughing and finishing with one tool.
Center cutting for plunging and ramping operations.
Unequal flute spacing for chatter-free machining at highest feed rates.
